@RadicalCartoons @HebrideanHecate @Ladyfat It is an interesting idea.
I often wonder why so many people join political parties, but I quickly remember the words of WS Gilbert:

I grew so rich that I was sent,
By a pocket borough into parliament,
I always voted at my party's call,
And never thought of thinking for myself at all,
I thought so little, they rewarded me,
By making me the ruler of the Queen's Navy.

and

When in that house MPs divide,
If they've a brain a cerebellum too,
They've got to leave that brain outside,
And vote just as their leaders tell 'em to.

It's a career path which appeals to people who don't want to think too hard, but like to appear virtuous.
We need to make it a vocation.
